abstract= {Contains 5 separate mean layer temperature datasets from NOAA NCEI:



Mean Layer Temperature - NOAA CDR

Configuration Item ID: 01B-25

The Mean Layer Temperature – NOAA Climate Data Record (CDR) provides long-term temperature measurements for a thick layer of the upper atmosphere. Input data comes from Mean Layer Temperature (MLT) level-1c swath radiances taken by the Microwave Sounding Unit (MSU), the Advanced Microwave Sounder Unit-A (AMSU-A) and the Advanced Technology Microwave Sounder (ATMS) aboard NOAA, NASA, and EUMETSAT satellites. The CDR was calibrated using the NOAA STAR Integrated Microwave Inter-Calibration Approach (IMICA) to remove calibration drifting errors. The final dataset incorporates inter-satellite bias corrections to ensure consistency, and adjustments that account for diurnal drift effect, differences between viewing angles, and channel frequency differences between sensors. The final record is a monthly global gridded dataset with 2.5°x2.5° Latitude/Longitude resolution, and extends from 1978–present.

Mean Layer Temperature - RSS CDR

Configuration Item ID : 01B-13

The Mean Layer Temperature - Remote Sensing Systems (RSS) Climate Data Record (CDR) integrates thermal emission from oxygen molecules measured at different frequencies from microwave sounders. These measurements provide a crucial element for long-term monitoring of atmospheric temperature, particularly in regions that lack high-quality radiosonde measurements. The final record provides global average and global anomaly maps at 2.5°x2.5° resolution, and extends from 1978–2023.

Mean Layer Temperature - UAH CDR

Configuration Item ID: 01B-10

The Mean Layer Temperature - University of Alabama Huntsville (UAH) Climate Data Record (CDR) provides monthly gridded data from microwave sensors onboard operational polar orbiting satellites. These satellites measure temperature anomalies of the atmospheric layer from the surface to roughly 10km, centered in the Lower Troposphere. The final CDR has been calibrated to include adjustments for spacecraft drift, orbital decay, instrument calibration and instrument biases when merging data from the various spacecraft. Mean Layer Temperatures centered in the mid-troposphere (0-15km) and in the lower stratosphere (10-25km) extend this dataset. The final record includes global monthly gridded temperature anomalies on a global 2.5°x2.5° grid extending from 1978–2023.


Mean Layer Temperature - UCAR (Lower Stratosphere) CDR

 Configuration Item ID: 01B-07

The Lower Stratosphere Mean Layer Temperatures (MLT) Climate Data Record (CDR) shows the long-term variation of Advanced Microwave Sounder Unit (AMSU) channel 9 brightness and Microwave Sounding Unit (MSU) channel 4 brightness measurements that peak in the Lower Stratosphere. These instrument signals are necessary to produce the monthly MLT of the Lower Stratosphere. Data (level-1b) from AMSU/MSU on board multiple satellites were calibrated using coincident Global Positioning System (GPS) Radio Occultation (RO) temperature profile measurements from 2001–present. The calibrated MSU/AMSU data from 2001–2014 serve as reference data to calibrate other overlapped MSU/AMSU data from 1980–2001. The final record has global coverage, and extends from 1986–2019.

Mean Layer Temperature - UCAR (Upper Troposphere and Lower Stratosphere) CDR

Configuration Item ID: 01B-14

The Upper Troposphere and Lower Stratosphere Mean Layer Temperature (MLT) Climate Data Record (CDR) provides calibrated MLT data spanning both atmospheric regions. Input comes from the long-term variation of Brightness Temperature (BT) measurements from Advanced Microwave Sounder Unit (AMSU) channel 7 and Microwave Sounding Unit (MSU) channel 3 that peak in the upper troposphere and lower stratosphere. These peaks provide the necessary signal to produce the monthly MLT for both atmospheric regions. The AMSU Data (level-1b) is calibrated with high-quality radiosonde observations identified by coincident Global Positioning System (GPS) Radio Occultation (RO) temperature profile measurements. The calibrated MSU/AMSU data in the period of 2001-2014 serve as reference data to calibrate other overlapped MSU/AMSU data from 1980-2001. The final record has global coverage, and extends from 1986–2019.
